MACHINE FOR MAKING DISHES OR TRAYS FROM VENEER-WOOD.-

SPEGIEICATION forming part of Letters Patent No. da mber 1909- Application filed March 7, 1900. Serial No. 7,658- (No model.)

of the Unit-ed States, residing at St. Joseph, in.

the county of Berrien and State of Michigan, have invented certain new and useful Improvements in Machines for Manufacturing Dishes or Trays from Veneer-Wood, of which the following is a full, clear, and exact description, reference being bad to the accompanying drawings, which form part of this specification.

My invention relates to certain improved features of machines for manufacturing dishes or trays from veneer-wood, by reason of which the construction and operation of said machines is simplified.

More particularly, my invention relates to certain novel features in the construction of the wire-stapling device, to an improved mannerof mounting and operating the dies whereby the number and extent of wearing-surfaces is reduced, to a novel method of operating the feed of the veneer-wood whereby said feed may be regulated to make any size of dish, and to certain other novelties in adjustment and operation, which will appear more fully in the following detailed description and in the claims.

In the accompanying drawings, Figure 1 is a front elevation of my improved machine. Fig. 2 is a side elevation looking at the left of Fig.1. Fig. 3 is a section of Fig.1 on line 3 3. The stapling device is left out of Figs. 2 and 3 for clearness and also because it is shown up fully in the other figures. Fig. 4 is a rear view of the feeding device. Fig. 5 is a detail of the mechanism for operating the feed of the wire for stapling. Fig. 6 is a front view of the wire-stapling device. Fig. 7 is a longitudinal section of same through the middle; Fig. 8, a plan view of same; Fig. 9, adetail of staple forming and driving slides; Fig. 10,

a cross-section of the shell for carrying said slides; Fig. 11,a detail ofthe mechanism for operating the stapling device; Figs. 12 and 14, details of the wire-feeding mechanism. Fig. 13 shows two details of the staple-clenching mechanism.

A A indicate the main frame of the machine, braced'at the bottom by the cross-pieces A A and carrying at the top the bedplate B,

each side with guides E E, beveled at the edge, in which travel the slides E, carrying at their upper ends the knife-bearing crosshead F. Secured to the cross-head in any suitable manner are the usual scoring and cutting knives G for forming the blank; but as there is nothing new about them further description of them is unnecessary. A reciprocating motion is imparted to the slides E E by the arms H H, pinionecl to said slides at one end at H and having their other ends provided with'ia loop which embraces the eccentric cams H" H, which i are mounted on the driving-shaft O.

A standard I, bolted to the frame of the machine, carries the mechanism for feeding the veneer-wood. Loosely mounted in this standard is a rock-shaft J, which has rigidly secured to its opposite ends in any convenient manner the arms K and K. A link L, pivotally connected to the arm K at one end and at the other end attached to the loop M, embracing the eccentric cam M, mounted on the shaft 0, imparts anoscillating movement to the arm K, which causes the shaft J to rock, thus oscillating backward and forward the arm K. Carried by the standard I is a shell I, supporting loosely the sliding bar J, which has pivotally connected to its forward end the presser-foot J, held down by the spring J. A link K, pivotally connected at one end to the arm K and at the other-to the sliding bar J, transmits the backwardand-forward motion of the arm K to the sliding bar J, and the sliding bar J through the presser-foot J in its forward movement feeds the necessary amount of veneer-wood to make a dish. It will be observed that the arm K is provided with a slot 0, and it is by means of this slot that the rate of feed of the veneer-wood is varied. The link L is pivotally v connected to the arm K by means of the pin too O, passing through the slot- O, andthis pin is held at any point in the slot 0 by the nut 0. Moving the pin 0 nearer tothe rockshaft J the effect of shortening the arm K. Now as the throw of the eccentric cam M is always the same the length of are through which the pin 0 travels must al ways he the same; but as the radius of the,

are is decreased by moving the pin 0 nearer the rock-shaft J the angle measured by said are is increased, thus increasing the throw of the arm K, and hence the amount of veneer: wood fed'by each forward movement of the presser-foot J. A long double spring-wire P, pivoted at P and held down by a small coil-spring P, holds the veneer-wood in contact with the bed-plate B and prevents it from sliding backward as the presser-foot J s rasgedha k to ak o d n fee ag n, The presser-foot J is provided with the usual teeth for gripping the veneer-wood. The bar .1 is provided with a number of holes Q for adjusting the position ofsaidbar J with reference to, the knives G.

As the veneer is fed by the mechanism described above the knife-hearing cross-head F descends and properly cuts and scores the dish forming blank in the usual manner. To assist the return of the cross-head to rise again in readiness to cut the next blank, a pin R is provided, secured at its upper end to the slide E, as seen in Fig 3, with itslower end passing througha hole in an offset R" of the frame A. A coil-spring R, extending be.- tween the head of the pin R and the ofiset R, is compressed by the descent of the slide E, and when the slide E starts lLp again its p s a is ed by the elasticity of the spring R. A like pin R. and spring R, are provided on the. opposite side of the machine for the other slide E.

"Next I shall pass to description of the manner of mounting the dies for forming the dish or tray.

The male die S is carried by the cnrved arm S, Which is pivoted to the back of the frame as follows: The arm S is in the form of aiweb, which being of the width of the machine at the rear decreases in front to a width sufficient to give a good bearing to the male die S. This web, is, Strengthened by the ribs S" and S, c'nlar in section, said section being slightly larger at the center, as seen in Fig. 4:. Each end of this. circular portion T is provided with a holeor socket into which fit the pins Tl; The saidpins T are threaded partly and screwed through the frame of the machine A, so that the bearing of the pins in the socket may be tightened or loosened by simply turning the pins T, and said pins are provided with the clamp-nutsT for holding them after they have been properly adjusted. It will be observed that the pins 'I" areslightly pointed, soas to give a true bearing.

"The manner above described of mounting the arm Siis the one I prefer, becausein this way friction at the fulcrum is reduced to a minimum, there is a minim um of wearing-sur- The rear end of the arm is ci r-,

face, and any loose play at the fulcrum which may result from wear at the ends of the pins T may be taken up by a slight turn of said pins However, as is readily seen, the pins '1" may be replaced by a single rod, which would pass completely through the circular part T of the arm 'S and be mounted in't he frame A. Such method of fulcruming the arm S is within the spirit of myinvention. The curved arm S is given an oscillating up-and-down motion in the following manner: Mounted on the shaft 0 is the eccentric earn 0, embraced by the loop or collar 0. The collar 0 is provided with a lug U, having andnternal thread into which works the threaded end of the rod U. A bifurcated block V is pivoted to an extension V of: the rib, S and is proided wi h. a smoo h Socket, tq hidt ceives the upper end of; the rod U. A setc ew U erv hold he. '06 n, position in the block V, and the nut U serves to a p at t e lower, and t w l th s be seen'that there isample means for adj l sting the vertical positien of the arm S, and there,-

re of the. poi t act on f e male. lie Of course any convenient manner of imparting the motion of the cam O to the arrn S will answer, and I do not wish to limit myself to the particular construction shown.

The male i s yi d ns y. up rt d in the, frame W, which is bolted t'o the knifebearing cross-heads F, and as the manner of m unting d f ma die s, eadi e n ro the drawings and is not new I shall: not describe it further, except as to the following: h r is prq ided. a g r a, ca ried on t e d. or p op ly ve -lappin he i ds the, h; ut nstead descending with he. male die after the dish has been fornred, as formerly, it is heldontot thewayas, follows: he r d. s ttach d. t s uppe smi h 1 short bar a carr in the rod b, which asses y '1 y hrough a hol in the emnw Pira ed e the frame W at b is a Zshaped bar bf, and a r d pi ta y mounted at tsl w re on theshaft c, (which carries the wirefeedg. mechan m, to e desc ed latch) is pi ota ly ttached a s pp ndftbthefz ape ar a Th p rations, f o lows: 7 As the male die. ascends itcatches the dish-forming blank coming from the knives, carries it up with it, and also the finger a,

'which causes the blank to fold properly. Now as the male die descends the natural tendency of the finger ais to descend with it; but whilethe dish was being formed the'crosshead, F has beenrising preparatory tocntting an t r blan nd ith it the f me W", wh s raised the point I), and thuscaused the lower end 6 ofthe Z -shaped bar b to come under the rodb. and support it. The rod 1) is thus sn pported until the male die has descended, when the cross-head F, descending to c nt another blank, causes the point I) to descend, and thus rotate theizeshaped bar b out of the wayo he i l ows he in er aw es end n ead ness to. fol t e next la kend of the staple-forming slide h.

The mechanism for stapling the blanks is in duplicate, as usual, a like mechanism be ing mounted on both sides of the machine, as is seen in Fig. 1, where I have lettered this mechanism generally X, special details of it being shown in Figs. 6, 7, 8, 9, and 10.

The staple forming and driving slides are mounted in a shell d, which is bolted to an angle-plate e, secured to the top of the frame A of the machine. A face-plate e is removably secured to the shell d by screws or bolts to enable the staple driving and forming slides to be readily got at. The wire for forming the staples is fed through the tube cl, which is formed on the shell d, into and partly through a transverse slotf' in the head-block f of the rocking barf, which is rockingly journaled on pin f, having bearing in the downward-extending flanges g g of the shell (1. This head-blockfis normally held in contact with the face-plate e, in position to receive the wire as it comes from the tube at, by a coil-springg, mounted in sockets in the rocking bar f" and the bottom of the shell.

it represents the slide by which the wire held by the head-block f is cut and bent to form the staple.

i represents the staple-driving slide, which carries at its upper end on its lower side the bifurcated block j and on its upper side the standards k k, in which are journaled the detent 7a, which normally engages the upper The faceplate is cut away at the top, as seen in Fig. 8, and has its two extending ends 6 beveled, and as the staple-driving slide 11 descends pins it, extending on each side of the detent k, strike these beveled ends 6, and in so doing raise the detent from its contact with the upper end of the staple-forming slide h, and thus allow the staple-driving slide 't' to descend by itself. A coil-spring 10" at the upper end of the detent tends to hold it in contact with the upper end of the staple-forming slide 71..

The bifurcated blockj has journaled at its lower end a roller Z, and as'the staple-driving slide descends this roller Z strikes the upper end of the rocking arm, and thus causes the head-block f to drop out of the way of the descending staple-driving slide 1'. The stapledriving slide 2' nearits upper end is provided with a slot 4;, through which passes the bolt 'm. Said bolt m is screwed into the upper end of the staple-forming slide h and has its head threaded for the entrance of a screw on the end of the pin a, which passes loosely through a hole in the block j. A coil-spring n is mounted on the pin n between the blockj and the head m of the nut m. The purpose of the spring a is to return the staple-forming slide it to its normal position with reference to the staple-driving slide after the staple has been Its tension may be regulated by a bell-crank pinioned to the plate e" at o and to the block r by a set-screw r, said block r being pivoted in the bifurcated blockj atj.

The head of the rod 19' is provided with holes 10" for the admission of an adjusting-pin, by

means of which the distance between the pivotal points 7" and p may be varied, thus varying the force of the impact of the'staple as" it is driven against the dish-forming blank.

A connecting-rod q is screwed at one end into the block q and at the other into a block g,

which is pivotally connected with the crank s, rigidly secured to the shaft 3.

manner and carries at its lower end a pin t, which works in a groove 6 in the face of the cam a. (See Figs. 1 and 11.) The groove t is of such shape that the shaft 5' is rocked through the pin 25 and arm 25, and this rock ing motion of the shaft 3, through the arm 8, imparts an oscillating motion to the rod g;

which in turn rocks the bell-crank lever o, and thus operates the staple forming and driving slides.

The wire is fed to the tubes d by the fol-i A shaft 0, journaled in the An arm t is keyed to the shaft 8 in any'convenient 14,) which are journaled in the sleeves 3 3.

Springs 9 9 are coiled about said shaft 8 8, having one end fastened to the shafts 8 8 in any convenient manner and the other end passing down and held by set-screws 10 10; Other feeder-wheels 5 5 are mounted on'said shafts 8 8 and hold the staple-forming wire against the feed-wheels 4 4 by reason of the springs 9 9 and the eccentric mounting of said shafts 8 8 in said shaft-s 8 8. By turn-' ing the shaft 0 the two sets of feederwheels are turned, and thus feed the wire to the tube d. Blocks 1l,mountedon extensions 12 from the sleeves 2 3,are provided with holes through which the wire passes to the feeder-wheels. The coils of'wire for making the staples may be supported in any convenient manner.

The mechanism for intermittently turning the shaft 0 is shownin Figs. 5 and 12; This consists of the link 13, pivoted to the upper end of the arm E, (on the right-hand side of the machine,) and having its other end pivoted to the lever 14, which has one end piv- 22 with a ratchet-wheel 21, rigidly secured to the shaft 0'. It will be readily seen that as the arm E oscillates up and down it will,

Fig. 13 shows the device for clenching the staples. On each side of the male. die is a slot covered by the plate 25., within which slot works the clenching mechanism. A short bar 27 isfbolted to. the inside of this plate and has rigidly secured to it the pins 28, slightly hollowed out at the top and extending through holes in a'second block 27, but not quite through said block. A s'cre'w passesloosely through block '26 and is screwed iE i Q. block Qi1.- p s :.sur qun hepi is28 a d normally tend to hold the block 21 with its upper edge slightly above. the surface of the die. I As the stapledriving slide descends and with it the staples the'ends of the staples pass into the holes in the block 27, and asthe driver continues to, descend it forces the block 27 down and brings the end of "the staples forcibly against the ends of the pins 2 8, which are slightly hollowed out, and thus cle'nches the staple.

The screw 29 is for regulating the tension of the springs, 30.
